Learn how to design and implement a topologically shielded lightning protection system with bonding, grounding and surge protection. This paper explains the roles and requirements of these components with citations from international codes and standards.
Lightning protection systems have been in use in one fashion or another for over two hundred and fifty years, well before electricity was harnessed as a usable form of power. In the past one ... • Grounding Electrode Subsystem • Equipotential Bonding Subsystem • Surge Protection Subsystem Figure 1. Representative LPS.
Lighting protection provides a path of least resistance for the lightning strike, preventing damage to the structure and its contents. This typically includes the installation of lightning rods (air terminals) on the roof, conductors to carry the lightning's electrical energy safely to the ground, grounding systems, and surge protection devices to safeguard electrical and electronic equipment ...
Lightning currents inherently want to ground—whether the proper systems are in place or not. A lightning strike, which is intercepted by an air terminal, must have its current transferred to the earth safely and seamlessly. The grounding system is the integral part of a modern electrical lightning protection system that must be dependable for ...
The objective of lightning protection is to preclude hazards to persons, structure, or buildings and their contents attributable to the effects of lightning. Protection measures to reduce physical damage depend mainly on the installation of both external lightning protection system (LPS) and internal LPS. An external LPS for structures and buildings against direct strikes basically comprises ...
About Grounding Lightning Protection Systems Standards Lightning Protection Systems: US NFPA 780 vs BS EN 62305:2006. Lightning Protection Systems are not only one of the most expensive infrastructure components of a building, but is also one of the least understood. In the United States, most industry and the government facilities are ...

GROUNDING SYSTEM AND LIGHTNING / GROUND FAULT PROTECTION 1 i INFO The information given is intended to provide basic grounding techniques and lightning protection. It is not intended to be a complete course on grounding or a guarantee against protection during a lightning strike situation. Please follow the National Electric Code (NEC) or the ...
While essential for daily operations, standard electrical grounding may not adequately address the sudden and immense energy spikes produced by lightning strikes. Specific lightning grounding systems are necessary to supplement standard electrical grounding, ensuring comprehensive protection against lightning-induced risks.
A comprehensive lightning protection system addresses this issue through equipotential bonding – the interconnection of all metallic building systems with the lightning protection grounding system. When all grounded systems are bonded together, it creates a common ground potential, ensuring the lightning current follows the intended path to ...
A grounding switch for lightning protection must take a large electric charge to the ground in a short time. At the same time, according to the “Lightning Protection Instructions RD 34.21.122-87”, the design of the ground electrode system is normative.
The question becomes “What is meant by a ground system?” The simple answer is a good connection to the earth to provide a low impedance path for unwanted currents or voltages that may be present. The NEC codes require grounding for protection from electrical shock and for lowering the effects of lightning discharge.
It involves installing a lightning protection system, typically consisting of lightning rods, unified grounding systems, bonding, and surge protectors. These components work together to provide a low impedance path of least resistance for lightning to follow, safely dissipating its energy into the ground.
A lightning protection system does not prevent lightning from striking. Instead, it provides a safe path for the lightning charge to reach the ground without causing damage to the structure. The system typically consists of lightning rods (or air terminals), conductors, ground terminations, and surge protection devices. ... The grounding system ...
Detailed requirements exist for type, spacing and more for various buildings, which can be found in the ERICO Lightning Protection Handbook. 3. Dissipate Current into the Earth . The reliable performance of the entire lightning protection system is dependent upon an effective earthing or grounding system.
